Masonry drill bit DeWalt DT9410-QZ — diameter 16 mm, for rotary hammer, 1 pc

DeWalt DT9410-QZ masonry drill bit with a 16 mm diameter is designed for use with rotary hammers on concrete, brick and other masonry materials. The bit features an EXTREME SDS‑Max-style geometry with a solid two‑cutter carbide tip supported by two additional cutting tips and a reinforced core. A four‑flute helix removes debris efficiently to preserve drilling speed and maintain consistent hole accuracy for anchor, fastener and conduit installations.

Advantages

The reinforced core and four‑flute helix improve impact stability and speed by evacuating chips effectively, reducing clogging during hammer drilling. The multi‑cutter carbide head combines a solid two‑cutter center with two flanking cutting tips to deliver fast penetration and prolonged tip life. Compatibility with SDS‑Max rotary hammers ensures secure bit retention and consistent power transfer for heavy‑duty applications.

Suitable for

• Drilling holes for anchors and fasteners in reinforced concrete
• Creating passages for conduits and pipes in masonry walls
• Installing fixtures in brick and natural or artificial stone
• General purpose demolition and construction drilling with a rotary hammer

How to use

Select a rotary hammer with an SDS‑Max chuck and secure the DeWalt DT9410‑QZ bit by fully inserting the shank until it locks. Mark the drilling position, set the hammer drill to the rotary hammer (hammer) mode and start at low speed to establish the pilot; then apply steady pressure and raise speed as appropriate for the material. Withdraw the bit periodically to clear debris if drilling deep holes, and avoid excessive lateral force to preserve tip life. Observe standard safety procedures including eye, ear and hand protection.

Usage recommendations

Use the bit for hammer drilling in concrete and masonry only with compatible SDS‑Max rotary hammers. For reinforced concrete, allow the carbide tip to wear in gradually and avoid prolonged idling under load. Keep the flutes clear of debris during long drilling runs to maintain performance and extend service life.
